Cone-shaped edible container

ABSTRACT

A cone-shaped edible container according to the present invention comprises: an edible outer shell, an edible inner shell, and an edible first adhesive layer provided between the outer shell and the inner shell to adhere the outer shell and the inner shell to each other. The outer shell and the inner shell are rolled into a cone shape in a state of being adhered to each other so as to have a basic structure of a cone shape. The outer shell forms the outermost side of the basic structure, and the inner shell has a stronger rigidity than the outer shell. Thus, assuming a cone-shaped structure implemented only by the outer shell, even if an external force of a magnitude capable of breaking the assumed structure is applied to the basic structure, the basic structure is maintained.

TECHNICAL FIELD

The present disclosure relates to a conical edible container, and moreparticularly, to a conical edible container including an outer shell, aninner shell, and an adhesive layer.

BACKGROUND ART

Modern people take various instant foods to save time in busy everydaylives.

In particular, Korean people who mainly eat rice prefer instant foodsusing fried rice most, but unlike hamburgers or hotdogs, instant foodsusing fried rice that are packaged in a form that may be convenientlytaken while the users are not seated have not been provided.

This is because it is difficult to carry fried rice due to hot heat andthe fried rice is fragile when it is heated by using a microwave rangeprovided in a convenient store or the like.

Fried rice that is frozen and processed in a plastic container or apaper container is packaged to make the fried rice preferred by Koreanpeople in the instant form, but the plastic container or the papercontainer has to be treated after the fried rice is taken, and becausethe plastic container or the paper container has to have a size that islarge enough to house fried rice to container the fried rice, a papercontainer of a large size is necessary.

In consideration of the problem, it also may be considered to allow thecontainer to simply house contents and make the container itself edible.Through this, the consumers may be provided with interests, the tastesof the consumers may be stimulated, and the convenience of separatelytreating the container after the foods are taken may be reduced.

However, to achieve this, a technology of providing an edible containerhaving a suitable strength is necessary.

DISCLOSURE Technical Problem

A main objective of the present disclosure is to provide an ediblecontainer provided with an interior space that may house contents, andto provide a conical edible container that has a suitable strength suchthat the structure thereof may be maintained.

The objectives of the present disclosure are not limited thereto, andother unmentioned effects of the present invention may be clearlyappreciated by those skilled in the art from the following descriptions.

Technical Solution

In order to solve the problems, there is provided a conical ediblecontainer including an edible outer shell, an edible inner shell that issmaller than the outer shell, and an edible first adhesive layerprovided between the outer shell and the inner shell to bond the outershell and the inner shell.

The outer shell and the inner shell may be wound in a conical shape in astate in which the outer shell and the inner shell are bonded to eachother to form a basic structure of the conical shape.

The outer shell may form an outermost side of the basic structure.

The inner shell may have a strength that is stronger than that of theouter shell such that the basic structure is maintained even when, withan assumption that the conical structure is implemented only by theouter shell, an external force of a magnitude, by which there is apossibility of the assumed structure being damaged, is applied to thebasic structure.

The conical edible container may further include a second adhesive layerprovided between an inner part of the outer shell and an outer part ofthe outer shell, which is superposed on the inner part, in the conicalstate to restrain the outer shell and the inner shell from beingreleased from the conical shape due to the inner shell having anelasticity that is stronger than that of the outer shell after the outershell and the inner shell are wound in the conical shape, whereby atleast parts of the outer shell are bonded to each other.

In an embodiment, the outer shell and the inner shell may haveproperties of making a bonding force of the second adhesive layer, whichbonds the parts of the outer shell, stronger than a bonding force of thesecond adhesive layer, which bonds parts of the inner shell, or abonding force of the second adhesive layer, which bonds the inner shelland the outer shell.

In an embodiment, the outer shell may include at least one selected froma group consisting of chlorella, green laver, sea staghorns, laver,agar-agar, seaweed, kelp, gulfweed, and fusiformis.

First Embodiment

FIG. 1 is a view illustrating an example of a product that uses aconical edible container according to the present disclosure. FIG. 2 isa view illustrating a conical edible container according to a firstembodiment of the present disclosure, which is viewed from one side.FIG. 3 is a view illustrating a state, in which a body sheet of theconical edible container according to the first embodiment of thepresent disclosure is unfolded. FIG. 4 is a cross-sectional view of theconical edible container of FIG. 2, taken along a vertical direction.

Referring to FIG. 1, a product containing contents R in a conical ediblecontainer according to the present disclosure may considered. Because aconical interior space is provided in the interior of the conical ediblecontainer, the contents R may be housed in the interior space. Forexample, the contents R may include rice.

It may be considered to surround at least a portion of the conicaledible container with a gripping sheet 5. The gripping sheet 5 may shella partial area including a portion corresponding to an apex of theconical edible container. In this case, because a hand may be preventedfrom directly contacting the conical edible container when the productis gripped by the hand, it is sanitary.

As illustrated in FIG. 1, because the gripping sheet 5 is configured tohave a conical shape and a portion of the gripping sheet 5, whichcorresponds to a bottom surface of the conical shape, is opened, theconical edible container may be inserted into the opened portion.

Referring to FIGS. 2, 3, and 4, the conical edible container 100according to the present embodiment includes an outer shell 110, aninner shell 120, and an adhesive layer 130.

The conical edible container 100 is made to have a conical spacestructure by winding the outer shell 110 and the inner shell 120 in astate in which the outer shell 110 and the inner shell 120 are bonded toeach other through the adhesive layer 130. The edible container 100 mayinclude a lower end, at which an apex is located, and an upper endincluding an opening such that foods are loaded.

The outer shell 110 may include an edible material. The outer shell 110may include a dry seaweed sheet.

The dry seaweed sheet is obtained by drying seaweeds themselves orflakes or powder of the seaweeds into a thin sheet form having anarbitrary shape, and green algae, such as chlorella, green laver, andsea staghorns, red algae such as layer and agar-agar, brown algae suchas seaweed, kelp, gulfweed, and fusiformis may be used as the seaweedsused as the material of the dry seaweed sheet alone or in a combinationthereof, and as a representative example, layer may be dried and usedalone or may be dried together with green laver, chlorella, and seaweed.In order to further improve the flavor of the seaweeds, variousseasonings may be further added to the seaweeds. For example, the outershell 110 may include seaweed.

The inner shell 120 may include an edible material. The inner shell 120may be a grain sheet. The grain sheet is a thin sheet having anarbitrary shape, and is manufactured of a grain material, such as ricepowder and/or starch, and water. The grain sheet may be manufactured byadditionally mixing rice powder with starch powder. Furthermore, theunique taste of a source material, such as shrimps, sesames, blacksesames, layer powder, anchovies, squids, or a combination thereof, maybe added and the chewing taste may be improved by adding the sourcematerial. In the grain sheet, for example, the content of the ricepowder may be 1 to 100 parts by weight with respect to 100 parts byweight of the content of the starch, and preferably, may be 1 to 50parts by weight, and more preferably, may be about 20 parts by weightwith respect to 100 parts by weight of the starch. The rice may bepolished rice, unpolished rice, red rice, green rice, and/or stickyrice. The starch may be selected from a group consisting of potatostarch, sweet potato starch, tapioca starch, corn starch, rice starch,and a combination thereof, and preferably, tapioca starch may beselected. According to an implementation of the present disclosure, agrain sheet manufactured of rice of 30 parts by weight with respect totapioca starch of 100 parts by weight may be used. The grain sheet maybe used after a grain sheet product that are on sale in the markets ormay be directly manufactured by using a conventional known method. Forexample, the grain sheet may include rice paper.

The inner shell 120 may have a property for reinforcing the outer shell110 that is relatively fragile. For example, the inner shell 120 may beformed of a material having a strength that is stronger than that of theouter shell 110. For example, the inner shell 120 may be formed of amaterial having an elasticity that is higher than that of the outershell 110. For example, the inner shell 120 may have a strength that isstrong enough to maintain the conical shape without using a separatesupport member because it is easily formed in the conical shape as thestrength thereof becomes lower in a state of a high content of moistureand the strength thereof is improved after being baked in a specificcondition. For example, the inner shell 120 may provide a hardness of1500 gf or more when it is baked in a condition of 150° C. to 200° C.and 5 minutes to 10 minutes. The hardness may provide a strength that issufficient enough to prevent the inner shell 120 from being easilybroken even though a person eats a food while gripping the food with ahand when contents of 50 g to 150 g are contained in the conical ediblecontainer.

The body sheet 100 may be manufactured by bonding the outer shell 110and the inner shell 120. The body sheet 100 may be manufactured byjoining one outer shell 110 and one inner shell 120, but also may bemanufactured by joining one or more outer shells 110 and one or moreinner shells 120. Then, at least one side surface of the outer shell 110may be cut to be larger than one side surface of the inner shell 120.For example, when both of the outer shell 110 and the inner shell 120are circular, the diameter of the outer shell 110 may be larger than thediameter of the inner shell 120 by 3 cm, in detail, by 2 cm, and in moredetail, by 1 cm.

The joining of the outer shell 110 and the inner shell 120, which isperformed in the process of manufacturing the body sheet 100, may beperformed according to any method that is sitologically allowed. Forexample, the body sheet 100 may be manufactured by applying the adhesivelayer 130 to at least one of the at least one outer shell 110 and the atleast one inner shell 120 and pressing the outer shell 110 and the innershell 120 after seaming them. Then, an adhesive that forms the adhesivelayer 130 may be an edible liquid having viscosity, and for example,water, salty water, a sugar solution, starch water, grain glue, and thelike may be used, and flour glue, rice glue, or sticky rice glue may beused as the grain glue. Furthermore, in order to improve a crispychewing taste of a finally manufactured dry seaweed snack, the adhesivemay minimally include water within a range of having viscosity.

The adhesive layer 130 may include a first adhesive layer 131 that bondsthe outer shell 110 and the inner shell 120, and a second adhesive layer132 that maintains the 3-dimensional shape of the edible container 100.The first adhesive layer 131 and the second adhesive layer 132 may be ofthe same material, but the present disclosure is not limited thereto.

Because the adhesive layer 130 includes a material in a liquid orsemi-solid state having viscosity, the strength of the adhesive layer130 may be decreased by providing moisture to the inner shell 120, aswell as the bonding force that bonds the outer shell 110 and the innershell 120, to facilitate bonding and formation of the inner shell 120.The adhesive layer 130 may provide a strength that is sufficient enoughto be prevented from being easily broken when a person eats a food whilegripping the food with a hand as the content of moisture of the adhesivelayer 130 become lower and the hardness of the adhesive layer 130becomes higher when the adhesive layer 130 is baked in a specificcondition. For example, the adhesive layer 130 may include glue of grainsubstances. For example, the glue of grain substances is a glue which isheated and in which rice powder and water are mixed, and the substancesand the concentration of the glue may be selected such that a hardnessof 1500 gf or more may be provided when the glue is baked in a conditionof 150° C. to 200° C. and 5 minutes to 10 minutes. For example, theadhesive layer 130 may include sticky rice paste.

In order to restrain the outer shell 110 and the inner shell 120 frombeing released from the conical shape due to the inner shell 120 havingthe elasticity that is stronger than that of the outer shell 110 afterthe outer shell 110 and the inner shell 120 are wound in the conicalshape, the second adhesive layer 132 may be provided between the outersurface of the outer shell 110 at the wound-in portions, and the innersurface of the outer shell 100 at the shelling portions and the innersurface of the inner shell 120. Through the arrangement, the secondadhesive layer 132 may provide a sufficient bonding force formaintaining the conical shape.

Referring to FIG. 3, the inner part of the outer shell 10, which is notshelled by the inner shell 120, may be defined as a part of the innersurface 111 of the outer shell, which is not bonded to the inner shell120, in a state in which the inner shell 120 and the outer shell 110,which are bonded to each other, are unfolded. That is, the inner part ofthe outer shell 110, which is not shelled by the inner shell 120, may bedefined as a part of the entire area of the inner surface 111 of theouter shell, which is located between an edge of the inner shell 120 andan edge of the outer shell 110.

The outer part of the outer shell superposed on the inner part may bedefined as an outer surface 112 of the outer shell, which issuperimposed on the inner part of the outer shell 110, which is notshelled by the inner shell 120, with respect to a direction that facesthe outer side from the center of the conical shape. That is, the outerpart of the outer shell 110, which is superimposed on the inner part,may be defined as a part of the outer surface 112 of the outer shell,which contacts the inner part of the outer shell 110, which is notshelled by the inner shell 111.

The outer shell 110 and the inner shell 120 may have properties ofmaking a bonding force of the adhesive layer 130, which bonds the partsof the outer shell, stronger than a bonding force of the adhesive layer130, which bonds parts of the inner shell 120, or a bonding force of theadhesive layer, which bonds the inner shell 120 and the outer shell 110.

For example, when the outer shell 110 includes laver, the inner shell120 includes rice paper, and the adhesive layer 130 includes glueincluding grains, the outer shell 110 and the inner shell 120 may haveproperties of making a bonding force of the adhesive layer 130, whichbonds the parts of the outer shell, stronger than a bonding force of theadhesive layer 130, which bonds parts of the inner shell 120, or abonding force of the adhesive layer, which bonds the inner shell 120 andthe outer shell 110.

An adhesive layer 132 may be further provided between portions of theouter surface 112 of the outer shell, which is superimposed on the innersurface 121 of the inner shell such that the inner shell 120 and theouter shell 110 are bonded to each other. The individual strengths ofthe inner shell 120 and the outer shell 110 may be improved, and acoupling force between the layer structures may be improved as well. Theedible container 100 formed through the process may have a hardness of1500 gf or more as a whole, and thus may sufficiently endure a repulsiveforce due to the elasticity of the inner shell 120 and an external forcetransmitted when a person grips the edible container 100.

The conical edible container is manufactured by baking the manufacturedconical body sheet 100. The above-described process of baking the bodysheet 100 is a process of realizing a crispy chewing taste in a finallymanufactured joined body by further removing moisture that is present inthe outer shell 110, the inner shell 120, the adhesive, and the likethat constitute the body sheet 100. Accordingly, as described above, theprocess of baking the body sheet 100 may be performed in an environment,for example, in an oven, in which moisture is not present, for example,in a temperature condition of 175° C. or more, 177° C. or more, 179° C.or more, or 180° C. or more, and 195° C. or less, 193° C. or less, 191°C. or less, or 190° C. or less, and for a period of time of 3 minutes ormore, 4 minutes or more, 5 minutes or more, or 6 minutes or more, and 15minutes or less, 13 minutes or less, 11 minutes or less, or 9 minutes orless. When the process of baking the body sheet 100 as described aboveis performed in a temperature condition of less than 175° C. or isperformed for a period of time of less than 3 minutes, the moisture inthe body sheet 100 does not sufficiently decrease and a crispy chewingtaste cannot be realized in the finally manufactured joined body, andwhen the process is performed in a temperature condition of more than195° C. or is performed for a period of time of more than 15 minutes,the seaweeds that constitute the outer shell 110 are burned out.

Meanwhile, another embodiment of the present disclosure may furtherinclude a process of forming the body sheet 100 by using a mold beforebaking the body sheet 100 as described above. For example, the bodysheet 100 may be formed in a conical shape by surrounding an outerperipheral surface of the mold having a conical shape with the bodysheet 100, by using the mold having the conical shape. Then, the outerperipheral surface of the mold may be surrounded such that the outershell 110 of the body sheet 100 is exposed to the outside.

When the process of forming the body sheet 100 is performed, in order toprevent the body sheet 100 from returning to the original state andmanufacture the conical shape as it is, the body sheet 100 may befurther joined by applying the adhesive to the superimposed portion ofthe body sheet 100 when the body sheet 100 surrounds the outerperipheral surface of the mold, and further, the body sheet 100 formedby using the mold may be baked together with the mold while the bodysheet 100 is mounted on the mold.

The conical shape manufactured by baking the body sheet together withthe mold while the body sheet is mounted on the mold may be separatedfrom the mold after being cooled while being mounted on the mold. Thecooling process is a process for preventing the conical shape from beingbroken when the conical shape is separated from the mold, and may beperformed in a temperature condition of 50° C. or less, 40° C. or less,30° C. or less, or a room temperature, for a period of time of 1 minuteor more, 3 minutes or more, 5 minutes or more, or 7 minutes or more, and20 minutes or less, 17 minutes or less, 15 minutes or less, or 13minutes or less. After the cooling process, the conical shape separatedfrom the mold may maintain the shape formed by the mold.

The hardness of the baked body sheet 100 may be 1500 g or more, 1700 gor more, 1900 g or more, or 2100 g or more, and may be 6000 g or less,5800 g or less, 5600 g or less, or 5500 g or less. When the hardness ofthe body sheet 100 is lower than 1500 g, the crispness of the finallymanufactured conical edible container is not sufficient so that thechewing taste is decreased, and when the hardness is higher than 6000 g,the finally manufactured conical edible container is too hard to betaken.

Referring to FIG. 2, the basic structure of the conical shape may beconfigured such that a ratio of the diameter (or the width W) of aportion corresponding to the bottom surface of the conical shape and theheight H from the bottom surface of the conical shape to the apex is avalue of 1:1 to 1:10. That is, the aspect ratio of the conical shape maybe 1:1 to 1:10. This may be properly selected in consideration of makingthe conical edible container such that it is gripped conveniently and ofmaking the conical edible container such that contents are appropriatelycontained in the interior of the conical edible container. For example,when the ratio of the width W and the height H is close to 1:10, it maybe easy to grip the conical edible container but an interior space thathouses the contents may be small, whereas when the ratio of the width Wand the height H is closer to 1:1, the interior space that may house thecontents with the conical edible container may be wide but it may bedifficult to grip the conical edible container.

The moisture in the outer shell 110 and the inner shell having theconical basic structure may be removed after heating when the outershell 110 and the inner shell are heated.

Generally, when the material is heated, the moisture escapes from thematerial and thus the strength of the material becomes higher and theelasticity of the material decreases instead.

For example, when the outer shell 110 is formed of laver, the innershell 120 is formed of rice paper, and the adhesive layer 130 is formedof glue including grain substances, the outer shell 110, the inner shell120, and the adhesive layer 130 are stuck to each other when the conicalbasic structure is heated, whereby coupling force may be improved andthe overall structure of the conical basic structure may be increased.Accordingly, in the conical basic structure formed by winding the outershell 110 and the inner shell 120, a state before the heating maycorrespond to a semi-product and a state after the heating maycorrespond to a finished product. However, this is only forclassification, and a finished product may be constituted by using theconical basic structure before the heating corresponding to thesemi-product.

The outer shell 110 and the inner shell 120 may have any shape of acircular shape, a rectangular shape, and a fan shape when beingunfolded.

Referring to FIG. 3, the outer shell 110 and the inner shell 120 havingcircular shapes as a whole while being unfolded may be prepared.

In an embodiment, the outer shell 110 and the inner shell 120 arearranged to form concentric circles, and may be bonded to each other bythe first adhesive layer 131. That is, the outer shell 110 and the innershell 120 may be bonded to each other such that the center O1 of theouter shell and the center O2 of the inner shell coincide with eachother.

The outer shell 110 and the inner shell 120 may be wound while beingbonded to each other, to form the conical edible container, and theouter shell 110 and the inner shell 120 are bonded to each other by thesecond adhesive layer 132 such that the conical shape is not released,whereby the edible container that maintains the conical basic structuremay be manufactured.

Furthermore, as described above, the strength (or hardness) of theconical edible container formed as described above may be increased bybaking the conical edible container in a specific condition.

The outer shell 110 may have a diameter that is larger than that of theinner shell 120. For example, the radius of the outer shell 110 may belarger than the radius of the inner shell 120 by a first distance D1.That is, the outer shell 110 and the inner shell 120 may be configuredsuch that the edge of the inner shell 120 and the edge of the outershell 110 are spaced apart from each other by the first distance D1.

The inner shell 120 may be bonded to the inner surface 111 of the outershell. That is, the outer surface 122 of the inner shell and the innersurface 111 of the outer shell may be bonded to each other by theadhesive layer.

A process of providing the conical basic structure by winding the innershell 120 and the outer shell 110 in the conical shape will be describedas follows.

The body sheet 100 may be manufactured by bonding the outer shell 110and the inner shell 120 by the first adhesive layer 131. The body sheet100 formed by bonding the inner shell 120 and the outer shell 110 by thefirst adhesive layer 131 may include a first wing part 100 a and asecond wing part 110 b divided by an imaginary line L1.

The first wing part 100 a and the second wing part 100 b may besuperimposed on each other while one point A1, at which the imaginaryline L1 meets an edge of the body sheet 100, is taken as the apex. Then,they may be superimposed on each other such that the first wing part 100a is located on the outer side of the second wing part 100 b or thesecond wing part 100 b is located on the outer side of the first wingpart 100 a.

The first wing part 100 a and the second wing part 100 b may be bondedto each other by the second adhesive layer 132 while being superimposedon each other to form the conical basic structure.

In the state in which the body sheet 100 forms the conical basicstructure, the conical shape of the body sheet 100 may be maintained bybalancing a force of unfolding the body sheet 100 by an elasticity ofthe inner shell 120 and a force of restraining the body sheet 100 frombeing unfolded, by a bonding force of the first wing part 100 a and thesecond wing part 100 b, in a state in which the body sheet 100 forms theconical shape. FIG. 4 is a cross-sectional view illustrating the conicalbasic structure according to the embodiment of the present disclosure,taken along a plane that is perpendicular to the bottom surface of theconical shape and passes the apex of the conical shape.

In the cross-section of FIG. 4, a layer that includes the outer shell110 and does not include the inner shell 120, a layer that includes theinner shell 120, the outer shell 110, and the first adhesive layer 131,and a layer that includes the outer shell 110 and does not include theinner shell 120 sequentially appear continuously or discontinuouslyalong a direction (a direction that faces the upper side from the lowerside) that faces a location corresponding to the bottom surface of theconical shape from a location corresponding to the apex of the conicalshape.

That is, the layer that includes the outer shell 110 and does notinclude the inner shell 120, the layer that includes the inner shell120, the outer shell 110, and the first adhesive layer 131, and thelayer that includes the outer shell 110 and does not include the innershell 120 may appear continuously, but other layers may further appearbetween the layers and the layers may appear sequentially.

Here, when a cross-section that appears when the conical basic structureis cut at a location that is between the location corresponding to thebottom surface of the conical shape and a location corresponding to theapex of the conical shape and within a second distance D2 from the apexof the conical shape or along a plane that is parallel to the bottomsurface is viewed, only the layer that includes the outer shell 110 butdoes not include the inner shell 120 appears.

In the embodiment, an area of a specific length from the apex of theconical shape may have a cross-sectional structure including only theouter shell 110. Then, the specific length of the area may be 0.01 cm to1.5 cm.

When the inner shell 120 is located at a point ranging the apex of theconical shape, the apex portion of the conical shape may becomerelatively thick when the conical basic structure is formed, or it maynot be easy to bond the apex portion of the conical shape.

In the embodiment, because the inner shell 120 is disposed also at alocation that is spaced apart from the apex portion of the conicalshape, the conical basic structure may be easily formed, and becauseparts of the outer shell 110 are bonded to each other, the bonding forcemay be improved.

However, according to occasions, the inner shell 120 may be disposed toextend to the apex portion of the conical shape. For example, when it isnecessary to prevent the contents contained in the conical ediblecontainer from directly contacting the outer shell 110, the inner shell120 may be disposed to extend to the apex portion of the conical shape.

Meanwhile, referring to FIG. 4, the first adhesive layer 131 is formedin an area between the inner shell 120 and the outer shell 110, but thepresent disclosure is not limited thereto, and the first adhesive layer131 may be formed in an area that is narrower than the inner surface 111of the outer shell and is wider than the outer surface 122 of the innershell with reference to the cross-section of FIG. 4.

FIG. 5 is a cross-sectional view taken along line A-A′ of FIG. 2. FIG. 6is a cross-sectional view taken along line B-B′ of FIG. 2. FIG. 7 is across-sectional view taken along line C-C′ of FIG. 2.

Hereinafter, the structure of the conical edible container according tothe embodiment of the present disclosure will be described withreference to FIGS. 5, 6, and 7.

FIG. 5 is a cross-sectional view that appears when the basic structureis cut along a plane that is parallel to the bottom surface between alocation corresponding to the bottom surface of the conical shape and alocation corresponding to the apex of the conical shape.

In the cross-section of FIG. 5, a layer La3, in which at least the innershell 120, the first adhesive layer 131, and the outer shell 110 aresequentially stacked, and a layer La2, in which at least the outer shell110, the second adhesive layer 132, and the outer shell 110 aresequentially stacked, appear in the circumferential direction of thecross-section in a direction (a radial direction Dr) that faces theouter side from the inner side.

The state in which at least the inner shell 120, the first adhesivelayer 131, and the outer shell 110 are sequentially stacked may bedefined as a state in which the layer, in which the inner shell 120, thefirst adhesive layer 131, and the outer shell 110 are sequentiallystacked, is basic but other layers may be further stacked.

For example, the layer, in which at least the inner shell 120, the firstadhesive layer 131, and the outer shell 110 are sequentially stacked,may include a layer, in which the inner shell 120, the first adhesivelayer 131, the outer shell 110, the second adhesive layer 132, and theouter shell 110 are sequentially stacked, a layer, in which the outershell 110, the inner shell 120, the first adhesive layer 131, and theouter shell 110 are sequentially stacked, and a layer, in which theouter shell 110, the second adhesive layer 132, the inner shell 120, thefirst adhesive layer 131, and the outer shell 110 are sequentiallystacked.

Similarly, the layer, in which at least the outer shell 110, the secondadhesive layer 132, and the outer shell 110 are sequentially stacked,may be defined as a layer, in which the outer shell 110, the secondadhesive layer 132, and the outer shell 110 are sequentially stacked andother layers are present or not present.

Referring to FIG. 5, in more detail, a layer La1, in which the innershell 120, the first adhesive layer 131, the outer shell 110, the secondadhesive layer 132, the inner shell 120, the first adhesive layer 131,and the outer shell 110 are sequentially stacked, a layer La2, in whichthe inner shell 120, the first adhesive layer 131, the outer shell 110,the second adhesive layer 132, and the outer shell 110 are sequentiallystacked, a layer La3, in which the inner shell 120, the first adhesivelayer 131, and the outer shell 110 are sequentially stacked, a layerLa4, in which the outer shell 110, the second adhesive layer 132, theinner shell 120, the first adhesive layer 131, and the outer shell 110are sequentially stacked may continuously appear along thecircumferential direction of the cross-section of FIG. 5 in the sequenceof the layer La1, the layer La2, the layer La3, and the layer La4 in theradial direction Dr.

In an embodiment, in the layer La1, the inner shell 120, the firstadhesive layer 131, the outer shell 110, the inner shell 120, the firstadhesive layer 131, and the outer shell 110 may be stacked. For example,when the adhesive layer 130 is not applied between the inner surface 121of the inner shell and the outer surface 112 of the outer shell, whichare superimposed on each other in the radial direction Dr, the innershell 120, the first adhesive layer 131, the outer shell 110, the innershell 120, the first adhesive layer 131, and the outer shell 110 may besequentially stacked in the layer La1.

In the embodiment, in the layer L4 a, the outer shell 110, the innershell 120, the first adhesive layer 131, and the outer shell 110 may besequentially stacked. For example, when the adhesive layer 130 is notapplied between the inner surface 121 of the inner shell and the outersurface 112 of the outer shell, which are superimposed on each other inthe radial direction Dr, the outer shell 110, the inner shell 120, thefirst adhesive layer 131, and the outer shell 110 may be sequentiallystacked in the layer La1.

Referring to FIG. 6, the layer La5, in which at least the outer shell110, the second adhesive layer 132, and the outer shell 110 aresequentially stacked in the radial direction Dr, and the layer La6including at least the outer shell 110 may appear along thecircumferential direction of the cross-section.

In an embodiment, when the outer shell 110 is wound a larger number oftimes, a layer, in which the second adhesive layer 132 and the outershell 110 are alternately repeated, appears.

Referring to FIG. 7, a layer La7, in which at least the outer shell 110,the second adhesive layer 132, and the outer shell 110 are sequentiallystacked, and a layer Lab, in which the inner shell 120, the firstadhesive layer 131, and the outer shell 110 are sequentially stacked,appears along the circumferential direction of the cross-section.

FIGS. 8, 9, and 10 are views illustrating modified embodiments of theconical edible container according to the first embodiment of thepresent disclosure.

Referring to FIG. 8, the inner shell 120 may be bonded to the innersurface 111 of the outer shell to be biased to any one side.

In the embodiment, the inner shell 120 and the outer shell 110 may bearranged such that the center O1 of the outer shell and the center O2 ofthe inner shell are spaced apart from each other with respect to theimaginary line L1 that crosses the outer shell 110.

In this case, when it is assumed that a distance between an edge of theouter shell 110 and an edge of the inner shell 120 is a third distanceD3 on the one side, to which the inner shell 120 is biased, and adistance between the edge of the outer shell 110 and the edge of theinner shell 120 is a fourth distance D4 on a side that is opposite sideto the side, to which the inner shell 120 is biased, the third distanceD3 may be the shortest one of the distances between the edge of theinner shell 120 and the edge of the outer shell 110 and the fourthdistance D4 may be the longest one of the distances between the edge ofthe inner shell 120 and the edge of the outer shell 110.

Referring to FIG. 9, the inner shell 120 and the outer shell 110 may bebonded to each other such that the edge of the inner shell 120 and theedge of the outer shell 110 contact each other at one point P1.

As illustrated in FIG. 9, a cross-section of the conical basic structureformed by winding the body sheet 100 formed by bonding the outer shell110 and the inner shell 120, in the conical shape, may be considered.

Here, when a cross-section that appears when the conical basis structureis cut at a location that is between the location corresponding to thebottom surface of the conical shape and a location corresponding to theapex of the conical shape and within a specific distance from the apexof the conical shape or along a plane that is parallel to the bottomsurface is viewed, a layer, in which at least the inner shell 110, thefirst adhesive layer 131, and the outer shell 110 are sequentiallystacked in a direction that faces the outer side from the inner side,appears.

That is, when the conical basic structure is formed by the body sheet100 provided as illustrated in FIG. 9, unlike the case in which theconical basic structure is formed by the body sheet 100 provided asillustrated in FIG. 3, a layer including the inner shell 120 necessarilyappears on a cross-section that appears when the basic structure is cutalong a plane that is parallel to the bottom surface within a specificdistance from the apex of the conical shape.

Referring to FIG. 10, in the bonded state, the outer shell 110 and theinner shell 120 are cut from one point of the edge of the outer shell110 to a central portion, at which the outer shell 110 and the innershell 120 are bonded to each other, the portions located on the oppositecircumferential sides of the cutting line C1 are superposed on eachother to be wound in a conical shape, and are bonded to each other bythe second adhesive layer 132 to form the conical basic structure.

The outer shell 110 and the inner shell may be bonded to each other suchthat the center O1 of the outer shell and the center O2 of the innershell are superimposed on each other, and in the state in which theouter shell 110 and the inner shell 120 are bonded to each other, anarea from one point of the edge of the outer shell 110 to pointscorresponding to the centers O1 and O2 of the outer shell 110 and theinner shell 120 may be cut.

The wing part 100 a and the wing part 100 b located on opposite sides ofthe cutting line C1 are superimposed on each other, and the conicalbasic structure, in which the same location as the centers O1 and O2 ofthe outer shell 110 and the inner shell 120 is the apex A1, may beformed.

When conical basic structure is formed by using the body sheet 100provided as in FIG. 10, the interior space in which the contents may becontained may be formed larger.

The inner shell 110′ may have a size that is smaller than that of theouter shell 120′. That is, the inner shell 120′ may be provided suchthat the edge of the inner shell 120′ is located at the more centralportion of the outer shell 110′ than the edge of the outer shell 110′.

The outer shell 110′ and the inner shell 120′ may be disposed such thatthe center O4 of the inner shell is located on an imaginary line L2 thatpasses through the center O3 of the outer shell and crosses the outershell 110′. That is, the outer shell 110′ and the inner shell 120′ maybe provided to be line-symmetrical to each other with respect to theimaginary line L2.

The description of the conical edible container according to the firstembodiment described with reference to FIGS. 1 to 7 may be applied tothe conical edible container according to the second embodimentdescribed with reference to FIG. 11. When the conical edible containeris formed by using the body sheet of FIG. 11, as in the conical ediblecontainer according to the first embodiment, the cross-section as inFIGS. 4 to 7 may appear.

FIG. 12 is a view illustrating a modified embodiment of the conicaledible container according to the second embodiment of the presentdisclosure.

The outer shell 110′ and the inner shell 120′ may be bonded to eachother such that the opposite sides 113′ and 114′ of the outer shell andthe opposite sides 123′ and 124′ of the inner shell are superimposed oneach other. The outer shell 110′ and the inner shell 120′ may be bondedto each other such that the arc 115′ of the outer shell and the arc 125′of the inner shell are spaced apart from each other by a specificdistance. That is, the inner shell 120′ and the outer shell 110′ may beconfigured such that the radius of the inner shell 120′ is smaller thanthe radius of the outer shell 110′, the center angle of the inner shell120′ and the center angle of the outer shell 110′ are the same, and thecenter O3 of the outer shell and the center O4 of the inner shell aresuperimposed on each other.

FIG. 13 is a cross-sectional view of the conical edible container ofFIG. 12 formed of a body sheet, taken along a vertical direction. FIG.14 is a cross-sectional view of the conical edible container of FIG. 12formed of a body sheet, taken along a widthwise direction.

FIG. 13 is a cross-section that appears when the conical basic structureis cut on a plane that is perpendicular to the conical bottom surfaceand passes the apex of the conical shape.

Referring to FIG. 13, a layer that includes the inner shell 120′, theouter shell 110′, and the first adhesive layer 131′ and a layer thatincludes the outer shell 110′ and the first adhesive layer 131′ but doesnot include the inner shell 120′ sequentially appear along a directionthat faces a location corresponding to the bottom surface of the conicalshape from a location corresponding to the apex of the conical shape.

That is, according to the present embodiment, a layer structure, inwhich the inner shell 120′ extends to the location corresponding to theapex of the conical shape, appears.

Referring to FIG. 14, a layer Lb1, in which at least the inner shell120′, the first adhesive layer 131′, and the outer shell 110′ aresequentially stacked in a direction that faces the outer side from theinner side, and a layer Lb2, in which at least the inner shell 120′, thefirst adhesive layer 131′, the outer shell 110′, the second adhesivelayer 132′, the inner shell 120′), the first adhesive layer 131′, andthe outer shell 110′ are sequentially stacked, appear along thecircumferential direction of the cross-section.

That is, according to the present embodiment, a layer, in which theinner shell 120′ and the outer shell 110′ are bonded to each other whilethe second adhesive layer 132′ being interposed therebetween.

Because the inner shell 120′ having a strength that is stronger thanthat of the outer shell 110′ is provided in the entire circumferentialarea of the body sheet when the conical edible container as in theembodiment described with reference to FIGS. 12 to 14 is provided, thestrength of the conical edible container may be improved further.

For example, when a bonding force when the inner shell 120′ and theouter shell 110′ are bonded to each other by the second adhesive layer132′ is stronger than a bonding force when parts of the inner shell 120′are bonded to each other by the second adhesive layer 132′ or a bondingforce when parts of the outer shell 110′ are bonded to each other by thesecond adhesive layer 132′, as in the present embodiment, it may beadvantageous for the structure of the conical edible container to bondthe inner shell 120′ and the outer shell 110′ with the second adhesivelayer 132′.
